20 August 2020: commandoo 2.0.1

This release version of commandoo supercedes an older version (1.0.1 March 2018). Numerous bug fixes, added features, "future proofing", (almost) mouseless usage, and much more. It is provided as an AppImage (see https://appimage.org) which allows it to run on a wide variety of gnu-linux distributions. This is "free" as in "freedom" software.

This is a GUI program designed to help the newcomer (and veteran) with the Linux Command Line Interface (CLI).

It is designed to be a 'helper' in the sense that one can store favorite / useful commands for quick retrieval and use later. It is designed to be a reference as well, it has a 'starter' database of 160+ Linux commands and examples. Notes and 'Threat Level' indexes are used to help the novice. Here is a glimpse of the Main Window, more images below.

It can be helpful for veterans as well: store those complex, meter long, command lines here, no need to develop it again, simply search for it and use it as is or adapt it to the current issue.

The program is not a terminal emulator, but gives its own advantages including: run and test (most) Command Lines directly, it can serve as a launcher program, it supports pkexec, it supports variables and asks at run time for the values, complex boolean searching is implemented as well a "simple" search, it supports text based storage and sqlite databases (your choice), it supports an unlimited number of databases as you like, and help is written directly into the program through toggle-able mouse-over hints.

commandoo v 2.0.1 README



An AppImage is a large file because it contains everything it needs to run on widely differing gnu-linux distros.

Simply download the AppImage and place it wherever you like in your home folder.

Then, mark it as executable and run it.

To mark it as executable using a file explorer: Right-click on the AppImage and choose properties, and tick the box that says something like "is executable".

Or use this command line in a terminal: chmod +x ~/PathToAppImage/NameOf.AppImage


And some more information...

The commandoo AppImage was developed in Kubuntu 20.04 as a qt5 application and has been tested on Fedora 32, Ubuntu 20.04, Kubuntu 18.04, Manjaro 20.04, and OpenSuse Leap 15.2. I've also been told it runs in Ubuntu 16.04. So, while designed in and for the recent 20.04 distros it will run on all the LTR distros too. In those cases I recommend using text based databases rather than the older sqlite libraries used by the older distros.

It doesn't matter if the distro has qt5 installed or not, it will still work because the AppImage is self-contained. Basically, it should work on any major distribution using any desktop environment (note: outside of Kubuntu 20.04 it will not pay any attention to theming, sadly. I will be working on this).

commandoo was built using free pascal and the Lazarus IDE. Thank you FPC and Lazarus.
